Well, that's part of the point. It's a tradeoff. Would there be an increased injury rate if SCUBA went the way of skiing? Would the SCUBA community be willing to accept an increased injury rate? How would an increased injury rate impact the industry? It's an accepted part of ski/ride culture that people get hurt daily.
In Colorado, the Skiers Responsibility Code is codified into state law. Ski patrol has authority to pull anyone's lift ticket for breaking the code. For example, if an area of a resort is closed and a skier ducks the rope to ski it anyway, they are breaking the law. Skiers are legally responsible for being competent. Would Florida be willing to have an authority decide which dive sites are open and closed each day and make it illegal to dive closed sites?
I am not exactly sure where I stand in all of this, but I do know that it might be for good reason that skiing and diving are regulated differently and that was the point of my post that you replied to.
